To (Ill @1710) t may ronuru:

.Ile it known that l.(u.\n|,1':s .\l. lon'rnn. a citizen of the looted States, residing; at (urrin ton inthc county ol Foster and State ol North Dakota, have invented rortain now and uscl'ul lml irovemcnts in Trivial Grainlanks, of \rluc the lollouing is a speedwation.

This invention relates to metallic buildings, and has. particular reference to l nockdown structures adapted especially for the storage of grain or the like.

The invention comprises certain spccilicf details of construction hereirmlter.l'ully de scribed and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly broken away, of a. grain bin constructed in accordance with the preferred embodiment of this invention; Fig. 2 isa transverse section Fig. 3 is adetail of onefiof the roof sections, and Fig.4 is alike view of the joint connecting two ofthe vertical side members.

'lhroughout the following detail descriptionanil on the several figures of the drawings, similar parts are ref rred to by like reference characters. I p This structure embodies a nlurality of ioincd togethe separately each to each, the general outline'ofthe. assembled parts being of any suitable form indicated herein. as being. circnlar. (nnnected to the bottom members are a plurality of angle pieces 11, one flange. of which is secured to the said bottom and the other flange of which projects vcrti(.-.ally therefrom. A socket piece 12- is secured in any suitable manner substantially centrally of the bottom.

The side or vertical walls of the structure arcomposed of any suitable number of cy indrical segments 13, joined together each to each by a eculiar locking means. As indicated said ocking means for the sidemem herscompriseshooks 14 and 14' connected respectively to the adjacent edges of the maln portions of the wall members iii, the I hook 14 extending inwardly and the other extending outwardly for interengageineut withthe inwardly projecting hook. 'lho embers 14 and 14 are preferably cocxtcn- SW6 vertically with the side walls 13 and are A series of able points with the inter oclcing members 1.4- and 1.4. As indicated herein said bolts 14" Specification of Letters Patent.

r 'lhe upper edges of the side wall members 13 are reinforced and bound by angle mem- 1 hers 15 as indicated in Fig. 1, and whose upper members will he formed so as to conform to the angle of the roof hereinafter described.

The roof portion is constructed in a peculiar manner, and by reference to Figs. 1 and 3 the sinnewillbc understood. Any suitable number of sector shaped sections 16 as may be desired will be employed to make up the roof. one of such sections being" indicated in perspective in Fig. -3. 'lhc materiaLtrom which each of these sections is fornredx is folded in a pGCUlllLI ll'IitIIIK-H' upon itself at its lateral edges to form reinforced vertical flanges 16, a portion of such flanges lying fiat by the use of a coi-nparatively small amount of material the structure is rendered very rigid and durable. The upper or smaller end body, so. as to extend vertically when the roof is assembled. Such portion indicated at .17 is provided with lateral flanges 17', and for a more effective bracing of the several portions the flanges 17' preferably extend bctween'thc portions of the flanges 16 as indicated at 18.
